To achieve more human-like proportions, an extra three sections of height were added, for a total of twenty-seven. However, none of the three components – legs, torso or head – are whole sections. The distance between the connectors beneath feet are equal to that of a minifigure, but the depth of the feet (toe to heel) was increased to six sections, equal to the height of a brick, allowing a more realistic proportion. That tiny bit of extra space means that legs can curve slightly at the back and the overall shape of the whole body is more realistic.

Minidolls are ½ of a brick (3 LU) taller than a minifigure, and their internal proportions are optimized for realism rather than an even number of units.
